06Application in ceramics
Using fumed silica instead of nano-Al2O3 to add to 95 porcelain can not only play the role of nanoparticles, but also the second phase particles, which not only improves the strength and toughness of ceramic materials, but also improves the hardness and elasticity of materials. Modulus and other properties, its effect is more ideal than adding Al2O3. Using fumed silica to composite ceramic substrates not only improves the compactness, toughness and smoothness of the substrates, but also greatly reduces the sintering temperature. In addition, the application effect of fumed silica in ceramic filters, corundum balls and other ceramic products is also very significant.

07Application in paper industry
In the paper industry, fumed silica products can be used as paper sizing agents, which can improve the whiteness and opacity of paper, and can improve oil resistance, abrasion resistance, hand feel, printability, and gloss. And it can also be used for printing drawings, which can make the surface of the paper good quality, the ink is stable, and the back is free of cracks, and can be used in azide paper to produce excellent blueprints, which can be used in coated paper instead of titanium dioxide. Adding 1-2% fumed silica product can reduce the weight of the paper, and the paper is thin, which can improve the strength, prevent the penetration of ink, and can also make the printed text clear and increase the opacity.

08 Application in toothpaste
Precipitated silica is the main variety of abrasives used in toothpaste at present. Precipitated silica has large total specific surface area, strong adsorption capacity, many adsorbed substances, and uniform particles, which is conducive to improving transparency. Because of its stable properties, non-toxic and harmless, it is a better toothpaste raw material. The refractive index of silica is 1.45 to 1.50, which is very close to the refractive index of other ingredients in toothpaste, so when mixed together, it acts as a clearing agent. This property is used to make clear toothpaste, a feature not found in any other abrasive.

09Application in cosmetics
The excellent properties of white carbon black, such as non-toxic, odorless and easy to color, make it widely used in the cosmetic industry. Silica is used in skin care and cosmetic products to give the skin a smooth and soft feel ("ball bearing effect"), resulting in a "soft focus effect" that evenly distributes the light hitting the skin surface, making it difficult to Wrinkles and blemishes in the skin are noticed. In addition, the thixotropy of silica can prevent pigment sedimentation, which can be used in products such as lipstick and nail polish.

10The application of silica in rubber shoes
The white carbon has high black and white degree and fine particles. The vulcanized rubber prepared by using transparent white carbon black has high transparency and can improve the comprehensive physical properties of the rubber compound. Therefore, white carbon black is widely used as the main reinforcing filler in high-end leather shoes and sports shoes. In the sole making material, especially in the transparent and translucent sole compound. It can improve the abrasion resistance, hardness, tensile strength and tear strength of the sole.
